So I’ve looked on the forums for info on the N1500, and read whatever info was available but still can’t come to a good conclusion. I have both blowers available, and planning to upgrade the bearings to spin the blower to 60k using a 3” RR pulley (possibly upgrade the impeller). So my question is which blower should I go with? I’m aiming for 500+++ whp on E85. Also, is belt tightening much easier on the SOS vs Comptech kit? I have both kits available for the install, debating which one to keep . Thanks in advance!

Novi 1200 can get you into 500whp range you just have to spin it 17-22psi or so and e85

Mate I have a brand new polished 1500 Ti Supercharger, never used. Comes with all new Vortech mounting plates and custom 8-Rib pulley set up with SOS Racing Heat exchanger and mounts etc... I also have the Cobra water pump.
My set up is identical to SIDEWAYS member on here.

You can have it for $2500

Yeah I've seen a couple cars get to 500whp with the N1200, but I'm wondering if the N1500 would be better for the job and maybe get there a little easier? Some of the comments I had seen previously regarding the N1500 stated the the blower was less efficient than the N1200 to 1150cfm or something like that, but where is this info coming from? I still haven't found any flow maps/charts that illustrate flow or psi per given RPM on either blower. So based on the specs below, is there a reason NOT to use the N1500? I have both blowers sitting on a shelf in my garage btw.

Novi 1200 RPM: 52000PSI: 22CFM: 1150HP: 775
Novi 1500 RPM: 55000PSI: 26CFM: 12000HP: 825

I made 600 on 1200, that’s seeing 27/28bs a boost though.

I think it would be tougher using the 1500 mainly because for our motor it's not efficient as the 1200. There are flow charts posted here, however, I don't know which thread they are in. It was a big discussion, theory, and truth. Also consider that you can overspin the 1200 with ceramic bearings can produce comparable numbers. Another difficulty would be spinning the 1500 enough without getting belt slip.

1500 you would need to rig up a wastegate most likely so that it came on later in the rpm, or you'll get bad compressor surge.

Or you can get a 1200, and make 550-6 like me There's ways

How about getting a 2200R Novi and make some power? The smaller blowers are very limited. A good 8 rib pulley set-up will make it all possible.

AP1Chief

You'll need a SERIOUS wastegate bypass setup on a 2200 to reduce surge, at that point might as well go turbo lol

I am selling my Novi 1500Ti Model Supercharger Kit with 8-Rib Pulley set up. it's all brand new and identical to yours as you know.

Do you know anyone who would want to buy this?
